1 INTRODUCTION

The 1492 programmable circular chart recorder measures,displays and records signals from any of the following inputtypes:

Thermocouple (THC)Resistance thermometer (RTD)Linear current or voltageNon-linear current or voltage from temperature transmittersSquare law and power root, current and voltageOther variables transduced to an acceptable current, voltage

or resistance level

The 1492 recorder is available in one-, two-, and three-channelversions with up to 6 output relays allocated to six set pointswhich in turn may be allocated to any channel or channels.

The recorder is microprocessor-based and requires no rangingcomponents. The input mode may be changed by repositioninga link on the printed circuit board and all other changes toinstrument operation are effected by a simple programmingsequence. Chart revolution time may be programmed in steps ofone hour, from a minimum of 1hr/revolution up to 168hr/revolution.

The recorder may be wall- or panel-mounted or fitted into acarrying stand. A post mounting kit is also available.

4 ELECTRICAL CONNECTIONS

WARNING. Before making any connections, ensure that thepower supply, any high voltage power- operated control circuitsand any high common mode voltages are switched off.

1. CAUTION. To avoid damage to multichannel recorders, highcommon mode voltages up to 250V r.m.s. max. must bepresent on all channels at all times, or not at all.

The maximum channel-to-channel voltage (between anytwo channels) must not exceed 12.5V or permanent damageto the instrument's input circuitry may occur. To prevent suchdamage the negative terminals on all inputs are linked – seeFigs. 4.3 to 4.6.

For applications where the available 12.5V isolation isrequired, the link(s) between the relevant channel and theother channel(s) must be removed.

If inter-channel isolation is required and the channel tochannel voltage rises above 12.5V then use of the type 'K'isolated input module is recommended. See section 4.4.

2. If the recorder is to be re-programmed before use, ensurethat the programming is complete before making any processsignal connections – see Section 8.

3. If the input type on any channel differs from that specified onthe program card, see Section 4.3.1.

4.1 Access to Terminals – Fig. 4.1Unlock and open the door, release the chassis and swing itforward – see Fig. 2.1 on page 2.

1 Identify the signal connections terminal block.

2 Identify the module(s) connections terminal block(s) (if fitted)

To gain access to the power supply connections terminal block:

3 Undo the knurled captive screw retaining the protectioncover and remove the cover. Take care not to stress theearthing cable connecting cover to case.

4 Identify the power supply terminal block.

4.2 Connections, Generala) The terminals accept cables of up to 2.5mm2 cross section.

b) Remove the 20mm diameter cable entry blanking plugs andreplace them with cable glands or conduit adaptors to suit theapplication.

c) Always route signal leads and power cables separately,preferably in earthed metal conduit. It is stronglyrecommended that, for signal inputs and relay connections,screened cable is used, with the screen connected to theearth stud(s) – see Fig. 4.1.

Fig. 4.2 Selecting the Signal Input Type

4.3 Signal ConnectionsIf a signal input is not connected or is not in use, even temporarily:

THC and mV inputs – short-circuit the + and – inputterminals on each channel (see Figs. 4.3 and 4.4).

RTD inputs – from standard tables obtain the resistiveequivalent of the temperature 'Range Zero' (noted on theProgram Card) and fit a resistor, approximately equal to orhigher than this value, across the input terminals for leads 1and 2. Link the terminals for leads 1 and 3 (see Fig. 4.5a).

V and mA inputs – it is not neccessary to make anyconnections to the input terminals (see Fig. 4.3).

4.3.1 Selecting the Signal Input Type – Fig. 4.2Plug-in links on the microprocessor p.c.b. select the input type;voltage, current or temperature (THC or RTD). If the input typediffers from that originally stated on the program card, the linksmust be re-positioned before making any connections and theinstrument must be re-programmed.

Fig. 4.8 Selecting the Isolated Signal Input Type

4.4 Isolated Signal ConnectionsUp to two isolated input modules, type K, may be fitted to therecorder, occupying module position 2, for channel 2, and/orposition 3 for channel 3 (see Fig. 4.1).

If an isolated input module is to be added, refer to Section 12.2for fitting instructions.

N.B.Isolated signal input connections must be made to the inputmodule(s) only. The respective input terminals for that channelon the processor board must be shorted out.

When changing a channel to or from an isolated signal inputmodule it is advisable to re-calibrate the recorder as describedin Section 10.

If a signal is not connected to an isolated input module, or is notin use, even temporarily, the procedures described in Section4.3 must be carried out.

The maximum channel-to-channel and channel-to-earth isolationvoltage is 2kV.

4.4.1 Selecting the Isolated Signal Input Type – Fig. 4.8Plug-in links on the isolated signal input module select the inputtype: voltage, current or temperature (THC orRTD).

If the input type differs from that originally stated on the programcard, the links must be re-positioned before making anyconnections and the instrument must be re-programmed, seeSection 8.

Notes.1. Continued pressure on the 'Raise' and 'Lower' switches

causes the rate of change of the displayed value to increase.To make small adjustments press the switches momentarily.Operation of the 'Raise' and 'Lower' switches duringprogramming causes the value or parameter being changedto flash until the 'Enter' switch is pressed. If left flashing forapproximately five minutes the display reverts to its originalvalue.

2. The 'Enter' switch must be operated each time a parameteror value is changed otherwise, on advancing to the nextparameter, the value reverts to that originally displayed.

5.2 Display – Fig.5.1A 20-character 5 x 7 dot-matrix, blue-filtered, vacuum fluorescentdisplay is used for display of all operating and programmingparameters.

5.2.1 Broken SensorThe position of broken sensor symbols on the display identifiesthe channel affected – see Fig. 5.1.

6 SETTING UP

6.1 Recorder Start-upCAUTION. Ensure that all connections, especially to the earthstud, are made correctly.

Check that:a) The input sensors are correctly installed.

b) The red pen tip coincides with the correct time line on thechart – see step 5 below. (To avoid collision the green penwrites approximately 4mm ahead of the red pen and the bluepen writes approximately 4mm behind the red pen, withrespect to time.)

Note. Only the red pen can follow precisely the time line onthe chart, since the other pen traces are at different radii fromthe common pivot. On instruments fitted with an event penthe event marker draws on the same time line as the red pen.

Switch on the supply to the instrument, any power-operatedcontrol circuits and the input signals and wait for the pens tosettle. (Pen lifting, referencing and lowering occur automaticallywhen the power is first switched on.) 'TEST IN PROGRESS' isdisplayed for approximately five seconds to allow for internalreferencing. The recorder then reverts to a display of themeasured value(s) – see Section 7.1.

6.2 Fitting the Chart – Fig. 6.1Ensure the power supply is on.

1 Press the 'Pen Lift' switch.

2 Lift the chart clamp and remove the old chart, if the recorderis already in use.

3 Fit the new chart on to the spindle, ensuring that it is beneathall the pen lifter arms.

4 Locate the lower edges of the chart in the retaining slots andthe upper edge under the control panel.

5 Rotate the chart on the spindle until it is positioned for correcttime recording by the red pen. Use the marker on the chassisas a guide only.

6 Lower the chart clamp and press on it firmly to ensure that thetwo locating pins pierce the paper.

If the instrument is already in use press the pen 'Raise/Lower'switch, otherwise proceed to Section 7.

6.3 Fitting the Pen Capsule(s) – Fig. 6.2

With the power supply to the instrument turned on operate the'Pen Lift' switch – see Fig. 5.1.


1 Gently pull each individual pen arm down off the bracket,taking care not to bend the arms.

2 Remove the spent capsule by sliding it up the pen arm.

3 Fit a new capsule to the arm by sliding the 'dove-tail' on thecapsule into the slot in the pen arm. Pen arms are identifiedby the coloured mouldings at the top of each arm; red (No.1 pen), green (No. 2 pen), and blue (No. 3 pen). Theappropriate coloured ink capsule must be used.

4 Hold the new pen capsule and gently twist and pull the capfrom the pen fibre tip.

5 Slide the pen arm and capsule assembly on to the appropriatepen arm bracket until it clips into place, ensuring that eacharm is positioned just above its own pen lifter bar. The greenpen arm fits the pen arm bracket adjacent to the chart, the redpen arm fits the central bracket and the blue pen arm fits theupper bracket.

Press the 'Pen Lift' switch to lower the pens, and ensure that thepens make contact with the chart and, on multi-pen instruments,that they do not collide when the pen lifter is operated and thepens traverse the chart. If collision occurs the pen arms havebeen bent, or fitted incorrectly, and this damage must be carefullyrectified.

In normal operation the measured values for all channels are displayed in an 'auto-advancing' sequence (Operating Page 1). Eachparameter can be held for viewing by operating the 'Parameter Advance' switch – see Fig. 5.1.

Operating the 'Page Advance' switch selects a second Operating Page (Operating Page 2) for viewing or changing the alarm setpoints. Required changes to the set point values are made using the 'Raise' and 'Lower' switches see Fig. 5.1.

A further series of pages can be selected using the 'Channel' and 'Page Advance' switches if the Security Link is enabled – see Figs.5.1, 8.1 and 8.2 on pages 16, 22 and 23.

8 PROGRAMMING

8.1 Programming, Generala) When changing the input type it may be necessary to

reposition the input type selection links accordingly – seeSection 4.3.1.

b) Ensure that programming is enabled – see Section 8.2.

8.2 Program Security Link – Fig. 8.1A plug-in link is used to prevent unauthorised programming ofthe instrument, by preventing access to the Programming Pages– see Fig. 8.2.


1 Identify the link.

2 Enable or disable the Program Pages, as required.

With programming disabled any operation of the 'Channel'switch initiates 'PROGRAM DISABLED' to be displayed for a fewseconds.

8.3 To Change the Program, PreparationOpen the door, release the chassis and swing it forward – seeFig. 2.1.

Ensure that:

a) Input links are correctly positioned – see Fig. 4.2 (or Fig. 4.9for isolated inputs).

b) External alarm/control circuits are isolated if inadvertentoperation during programming is undesirable.

Any changes to the operating parameters are made using the'Raise', 'Lower', 'Decimal Point' and 'Enter', switches see Fig.5.1.

Carry out all programming, other than calibration (see Section10) with the pens lifted. If the pens drop during programming,operate the 'Pen Lift' switch – see Fig. 5.1.

When programming is complete disable the Programming Pages(Section 8.2) and recalibrate the instrument, see Section 10.

8.11.4 Event Pen RangesIf a 1492 recorder with an event pen is using a standard chart, i. e. with a writing width of 105mm, the range and display full scalevalues for the variable pens must be set as described below:

Zero-based rangesOn the input page set Range Full Scale and/or Lineariser Full Scale to 96% of the full scale input value.On the Display page, set Display Full Scale to 96% of the variable represented by the full scale signal input.

Offset-zero rangesCalculate the Range Full Scale and Display Full Scale settings by using the actual input or display span values rather than fullscale; i.e. Range Full Scale would be 0.96 (input full scale – input min.) + input min.

Example. For an input of 4 to 20mA corresponding to a temperature range of 100 to 300°C from a type K thermocouple:

Lineariser Full Scale = 0.96 [300 – 100] + 100= 192 + 100= 292

Range Full Scale = mV equivalent of 292 – 100300 – 100 x 16 + 4

= 11.876 – 4.09512.207 – 4.095 x 16 + 4

= 7.7818.112 x 16 + 4

= 0.9592 x 16 + 4

= 15.35 + 4

= 19.35 mA

The above alternative setting procedures for Range Full Scale and Display Full Scale are not necessary if a chart with a writingwidth of 100mm is used.

9 SIMPLE FAULT FINDING

If the recorder does not appear to be working satisfactorily carryout the checks in the following table before contacting theService Organisation.

Are all the connections made correctly?

Is there power to the instrument?

Is there a signal at the input terminals?

Does an external relay fail to de-energise? If so see Section9.1, following.

9.1 Arc Suppression Capacitors – Fig. 9.1Arc suppression capacitors are fitted across the contacts of thealarm/control relays. If these contacts are used to operateexternal relays, the capacitor leakage current may be sufficientto prevent the external relay from de-energising. If so, switch offthe power supply and external alarm circuits. Identify theappropriate relay module – see Figs. 4.14a, 4.14b and 4.15b.Remove the four screws retaining the p.c.b. and carefullyunplug it.

CAUTION.The connection pins at the top of the p.c.b. are very fragile andcare must be taken not to bend or damage them.

Unsolder the appropriate capacitors as shown in Fig. 9.1 andrefit the module.

10 CALIBRATION

The recorder should be calibrated annually or following a changeto instrument operation. The pen arm length must be checked,and adjusted if necessary, before making any electricaladjustments.

10.1 Calibration, GeneralSwitch off the power supply. Connect the instrument to a signalsource or resistance box of known accuracy, suitable forsimulation over the entire input range, to the input terminals –see Section 4.3.

For thermocouple inputs, connect the millivolt sourceusing appropriate compensating cable – see Table 1.

For 2-lead resistance thermometers the resistance boxmay be connected at the sensor end of the leads or the leadresistance added to calibration values – see Section 10.3.

For all other inputs connect using copper wire.

Switch on the power supply.

10.2 Pen Arm Length AdjustmentIf the pen arm length is incorrect the pen does not record thecorrect time at all positions on the chart.

a) With reference to Fig. 8.2, select the Input and RecordingConditions Page, make a note of the Chart Time and thenreset it to 168hr/rev. Store using the 'Enter' switch.

b) Ensure that the pens are touching the chart and that the timeline marker on the chassis indicates the correct time line onthe chart – see Fig. 6.1.

c) Increase the channel 1 input signal from zero to full scale,within a period of 10 seconds, to draw an arc on the chart. Fortemperature inputs apply the equivalent millivolt or resistancevalues obtained from standard tables.

If the trace does not follow the time line the error must becorrected by adjusting the pen arm length as follows:

With reference to Fig. 9.2:1 Slacken the clamp screw.

2 Slide the pen arm in or out of the moulding, as necessary.

3 Retighten the clamp screw on completion.

Make similar adjustments to the green and blue pen arms, asapplicable. Ensure that the green pen records approximately4mm ahead of the red pen and the blue pen records approximately4mm behind the red pen (with respect to time) over the full chartwidth.

Note. Only the red pen can follow precisely the time line on thechart, since the radii of the other pens draw different loci. Oninstruments fitted with event marker the event pen draws on thesame time line as the red pen.

Reprogram the original chart time noted at a), above and storeusing the 'Enter' switch.

10.4 Calibration Page (Manual Procedure)The procedures detailed in this section are for manual calibration at the normal range zero and full scale limits. However themanual calibration procedure also facilitates calibration of the instrument at selected points within the range other than zeroand full scale.

As a general rule, spot calibration values should be:

<50% of range span value when using Calibrate Range Zero parameters>50% of range span value when using Calibrate Range Full Scale parameters

This facility is particularly useful when optimum accuracy is required at ‘spot’ values within the range, e.g. for eliminatingthermocouple errors by connecting the thermocouple to the instrument and keeping it at a constant temperature for the spotcalibration.
